WEDGE-BOLT LOCK.

Specification of Letters Patent.

Patented Nov. 22, 1910.

Application filed October 18, 1909. Serial No. 523,373.

To all whom it may concern:

Be it known that I, LESLIE G. RoBLIN, a subject of the King of GreatBritain, and a resident of the city of London, in the county ofMiddlesex, in the Province of Ontario, Canada, have invented a new,useful, and Improved Wedge-Bolt Lock, of which the following is aspecification.

This invention relates to the wedge bolts of locomotives and to theholding of said bolts in place; and it consists of a collared wedge boltand lock for the driving box wedges of locomotives, which will hold themin place or position and prevent them from working loose, and it alsoconsists of the mproved construction and novel combmatlon of parts ofthe same as will be hereinafter fully set forth and described and thenpointed out in the claims.

Reference being had to the accompanying drawings forming part of thisspecification wherein Figure 1 is a side view of a collared wedge bolt,and a sectional view on the line, a, a,

' of Fig. 2, of the adjacent parts of a locomotive embodying myinvention. Fig. 2 is an end view of Fig. 1. Fig. 3 is a detail plan viewlooking downward on the line, b, b, of Fig. 2. Fig. 4 is a detailperspective View of the device which prevents the wedge bolts fromworking loose. Fig. 5 is a front View of a locomotive axle and supportsembodying my invention. Fig. 6 is a detail side view of my inventionillustrating a modification of the device which prevents the wedge boltsfrom working loose. Fig. 7 is a cross sectional view of same on the line0, c, of Fig. 6. Fig. 8 is a plan view of the wedge bolt lock shown inFig. 6. Fig. 9 is another detail plan view on the line b, b, of Fig. 2,illustrating another modification of my invention which prevents wedgebolts from working loose.

In the accompanying drawings, the numeral 1 indicates the axle of thelocomotive, 2 the oil cellar, 3 the brass bearing and 4 the box thereof.This box 4 has flanges d, which clasp the shoe 5 on one side and thewedge 6 on the other side, and said shoe 5 has similar flanges (Z, whichclasp the ad jacent pedestal jaw 7 on one side, and said wedge 6 hassimilar flanges, cl, which clasp the adjacent pedestal jaw 7 on theother side of the axle to prevent lateral movement of the axle box 4.The wedge 6 has an inclined plane, 6, on one side so that the flanges,d, of this wedge 6 are wider at the top than at the bottom, and theadjacent pedestal jaw has a corresponding inclined plane, f, on one sideas shown in Figs. 1 and 5.

8 is a pedestal brace which is fitted to and inserted between the lowerportions of the pedestal jaws 7 as shown in Fig. 5; and 9 is a pedestalbrace bolt provided with an enlarged head, 9, at one end and with a nut,it, screwed or otherwise secured 011 the other screw threaded end, 2',of said pedestal brace bolt 9. This pedestal brace bolt 9 is fitted toand inserted in a bolt hole, j, which extends through the pedestal jaws7 and through the pedestal brace 8. And the pedestal brace 8 hasenlarged ends, is, and flanges, (Z, for strength and for attachment toassist in holding the pedestal brace 8 in contact with the pedestal jaws7.

10 indicates holes which extend horizontally through the wedge 6, and 11indicates holes which extend vertically through the enlarged ends, is,of the pedestal brace 8, and 12 indicates vertical sockets in the wedge6, in line with the holes 11.

13 indicate internal screw threaded nuts which are placed in saidhorizontal holes 10 of the wedge 6.

'14 indicate wedge bolts provided with threads m, a, at each end, with ashouldered collar 15 and with a round collar 16, which collars 15 and 16may be formed integral with or secured to said bolt 14 as desired.

The upper screw thread, m, engages with the internal screw threaded nut13, and the lower screw threaded end, it, engages with the internalscrew threaded nut 17; and through a pin hole 18 formed in this nut 17and the wedge bolt 14 a pin 19 is inserted, as shown in Figs. 1, 2 and5.

20 designates a bolt lock or device provided with the shouldered holes21 which prevent the bolts 14 from turning.

The holes 11 in the enlarged portions, 70, of the pedestal brace 8, areslightly elongated to prevent the wedge bolts 14 from binding on thepedestal brace 8.

In the modification shown in Fig. 6 the wedge bolt 14 has a shoulderedhead 22 fixed on said bolt but the lower head of said bolt 14 may befixed or attached thereto as desired. And this head 22in Fig. 6 is heldup and prevented from turning or working loose by the device 23 providedwith shoulder 24, which is held in contact with the to do is ders untilit comes opposite the round pedestal brace 8 by the set screw 25,extending through the device 23 pedestal brace 8 and engaging with thepedestal brace bolt 9. In the modification shown in Fig. 9, a

cotter pin 26 extends through pin holes 27 formed in the wedge bolts 14to prevent the latter from turning or working loose.

When this invention is placed in position as shown in Figs. 1, 2 and 8,the shouldered openings 21' of the lock 20 engage with the f'shoulderedcollars 15 on the wedge bolt 14,

collar 16, then turn the wedge bolt 14 to take up this wear, and lowerthe lock 20 to its original position again as shown in said figures,when th1s lock 20 will posltlvely prevent the wedge bolt 14 from workingloose or turning in either the wedge 6 or pedestal brace 8. The purposeof the round shoulder '16, therefore, is not only to permit the lock -20to be raised but to prevent the wedge 6 from beinglined down ontheshoulder 15,

which would prevent the lifting of the lock 20 above the shoulderedcollar 15, which is necessary to ermit the turning of the bolt. In Figs.6, and 8 side, end and top views,

i and in Fig. 9, a plan view of modifications time a simple,

. and a wedge of this lock 20, are shown.

In Figs. 6, 7 and 8 a shouldered head holder 23, is shown, and in Fig. 9a cotter pin 26, is shown, which avoids and completely prevents thewedge bolt 14 from working loose or turning, and at the same strong anddurable device for this purpose is provided and one that will be notonly economical to manufacture but one that will be and that has beenfound to be positively eflicient in practical use.

Having thus described my invention, I claim: 7

1. A shouldered wedge bolt, in combination with a wedge bolt lock, andlocking pin.

2. A wedge bolt with a collar, in combination with a look, a locking pinand a wedge bolt head holder. 7
